<p>What is the policy for supported LLVM versions? I'm still using LLVM 10 in my builds, I'm curious how long I'll be able to do that.</p>

<p>There's no set policy, its a combination of best effort and age. In nearest future I can see us dropping LLVM 9 support due to age, and perhaps slightly later anything before LLVM 12 if we find NewPM to be a large enough improvement that it warrants dropping support for older LLVM versions.</p>
